Current probe A622

automaticmeasurement

Overview
Tektronix current probe solutions provide a wide portfolio of AC/DC and AC-only probes for power and load analysis. Measurement ranges cover from microamp sensitivity to multi‑kiloamp models, with model-dependent bandwidth and rise-time performance. When paired with Tektronix oscilloscopes, many probes support automatic readout and scaling to simplify volts→amps conversion.

Highlights

• Broad selection of AC/DC and AC-only current probes
• Measurement capability from µA sensitivity up to 3,000 A (model dependent)
• Bandwidth options up to 2 GHz for high-frequency applications
• High clamp sensitivity down to ~1 mA on selected models
• Selected products carry third‑party safety certifications (UL, CSA, ETL)
• Models with bare‑wire voltage ratings and dedicated high‑current clamps available
• Automatic readout and scaling with Tektronix oscilloscopes where supported

Notes on usage and compatibility
Many probes require specific amplifiers, adapters, or terminations (for example TCPA series amplifiers, TCA/TCA‑BNC adapters, 50 Ω feed‑through part #011‑0049‑0X, TekProbe cables) to interface with certain oscilloscope families. Compatibility and necessary accessories are model dependent and listed per model in technical datasheets.
